It is a device that are used by many people for protection of the eyes, nose and mouth from splashes, sprays, and spatter of body fluids. Face protection comes in many different varieties and provides different kinds of protection for different hazardous situations such as flying objects and road debris, chemical splashes (in laboratory or industry), or potentially infectious materials (in medical and laboratory environments).and also like present times in which we are fighting against COVID 19 (Coronavirus).
COMPONENTS OF FACE SHIELD
This face shields material is made up from a polycarbonate, propionate, acetate, polyethylene terephthalate glycol (PETG) and steel or nylon mesh. It is because of the spread of Coronavirus (COVID 19) that its demand has increased numerous times causing scarcity of face shield in market.

Types of Face Shield
Face Shields are manufactured through two process. They are as following:
- Extrusion Molding: Face shields cut from extrusion sheets provide better impact and resistance as extrusion sheets are made of high molecular weight plastic pellets therefore it provides better melt flowing property.
- Injection molding: Injection molded face shields have less resistance as compared to extrusion molded face shields. Also injection molded face shields must use lower molecular weight plastic pellets
This can be explained with following example, even face shields 0.8 mm thick made of extrusion polycarbonate sheets can withstand the impact of a 6 mm nominal diameter steel ball traveling at the speed 120 m/s (European standard, protection against high-speed particles – medium energy impact), while injection molding face shields must have at least 1.5 mm thickness to withstand the same impact. But injection molding can provide more complicated shape than extrusion.
Needs of face shield
- This time world is fighting against COVID 19 (Coronavirus) which is spread from one person to another through small droplets from nose or mouth of infected person, whenever infected person speaks, sneezes, or coughs it releases coronavirus droplets into the atmosphere and they can be easily inhaled by any nearby person, therefore to stop the spread one needs to cover their mouth and nose so that coronavirus does not enter their respiratory system. Thus to fight COVID 19 (Coronavirus) one need to wear face shield. Face shield is considered as Personal Protection equipment is an added equipment for protection from harmful microorganisms. It is also very affordable and reliable and being mandatory by CDC its demand has increased. Face shield is one of the most important measure to protect our frontline healthcare professionals and prevent the spread of COVID 19. It is an integral part of healthcare environment.
